I need help whit trying to convince my friend not to do something! help!!?

Tell her how you feel! If you really want her back, try to arrange plans for you and her to do like go to the movies or something instead of her going out to drink.

But if I were you, I'd arrange plans and soften her up before you tell her how you feel, so you'll have a better chance of her denying it.

Hope I helped!

Out of the blue take her some flowers and candy. With a message tied to the flowers, tell her you love her and you want her back. If she were to go back with you she'd make you the happiest guy on the planet earth. (Girls like that) Start taking her out to the movies, out to eat, whatever... but get her the heck away from those other people before she ends up dead. I also want to point out one last crappy thing. You can only do what you can do. It's up to her to do the rest so if it doesn't go your way, at least you have a clear mind that you did all you can do. Best wishes :-) ~Amy

You really care for her don't you, you gotta try and stop her. Get her alone and tell her that's this isn't right, that she's gonna muck her life up so badly that she will get to a point of no return...and that's a place no one wants to be. Make her see sense, tell her you care for her deeply (cause she may be acting out cause you guys broke up) and that you will always be there for her. Tell her you want her back. You can only do so much, keep trying...try hard as you can not to give up.....but there's so far that you can go. you can only do so much and if it turns out she denies your pleas...you gotta walk away...you cant let it rule your life.

just tell her to come to her senses and to think whether that its going to do her any good

i would let her go her own way and i would find someone else to care about
